research An out-of-lab trial: a case example for the effect of intensive exercise on rhythms of human clock gene expression
Intense exercise at night can delay the body's internal clock gene expression by 2 to 4 hours.
research The effect of night shift work on the expression of clock genes in beard hair follicle cells
Night shift work disrupts the body's natural clock genes.
research The clock gene brain and muscle Arnt-like protein-1 (BMAL1) is involved in hair growth
A gene called BMAL1 plays a role in controlling hair growth.
research Chronic circadian misalignment is a risk factor for hair growth impairment
Disrupted sleep patterns from artificial light can slow hair growth and may lead to hair loss.
research Human and animal cells under influence of different lighting and stimulus
Different light affects cell functions and can help treat skin conditions.
research Overview of the Circadian Clock in the Hair Follicle Cycle
The circadian clock plays a key role in hair growth and its disruption can affect hair regeneration.
research MELATONIN
Melatonin may help with sleep issues, depression, and cancer, but more research is needed.
research Melatonin: A Cutaneous Perspective on its Production, Metabolism, and Functions
Melatonin may benefit skin health and could be a promising treatment in dermatology.
research Regenerating the skin: a task for the heterogeneous stem cell pool and surrounding niche
Different types of stem cells and their environments are key to skin repair and maintenance.
research The Modulatable Stem Cell Niche: Tissue Interactions during Hair and Feather Follicle Regeneration
The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.
research Module-based complexity formation: periodic patterning in feathers and hairs
The conclusion is that understanding how feathers and hairs pattern can help in developing hair regeneration treatments.
research ORIGINAL RESEARCH—ENDOCRINOLOGY: Comparison of the Steady‐State Pharmacokinetics, Metabolism, and Variability of a Transdermal Testosterone Patch Versus a Transdermal Testosterone Gel in Hypogonadal Men
The testosterone patch and gel are both effective, but they have different absorption patterns and effects on hormone levels.
research The transcriptional landscape of seasonal coat colour moult in the snowshoe hare
Researchers found genes that control hair color and growth change before the visible coat color changes in snowshoe hares.
research Transcriptomic regulation of seasonal coat color change in hares
Genes related to pigmentation, body rhythms, and behavior change during hares' seasonal coat color transition, with a common genetic mechanism in two hare species.
research Cosmeceutical Therapy: Engaging the Repercussions of UVR Photoaging on the Skin’s Circadian Rhythm
Natural skincare products may help reduce sun damage and support the skin's daily cycle.
research Photosensory Function, Reception and Response in Human Skin
Human skin responds to light with protective mechanisms, but more research is needed to understand these processes and their implications for health and therapy.
research Clock genes, hair growth and aging
Circadian clock genes are important for hair growth and may affect aging-related hair loss and graying.
research Epidermal stem cells: skin surveillance and clinical perspective
Epidermal stem cells are vital for skin healing and have potential for treating skin disorders.
research Exploring Hormone Therapy Effects on Reproduction and Health in Transgender Individuals
Hormone therapy improves mental well-being in transgender individuals but requires ongoing health monitoring.
research Light exposure and its applications in human health
Light exposure is crucial for health, helping prevent and treat illnesses.
research Clinical Snippets
Razor bumps are linked to a genetic variant, misoprostol helps erythromelalgia pain, steroid ointments don't affect skin rhythms, and certain antibodies are common in localized scleroderma.
research The effects of extended photoperiod and warmth on hair growth in ponies and horses at different times of year
Timing of light therapy affects horse coat growth, with photoperiod being crucial.
research An integrative view of mammalian seasonal neuroendocrinology
The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.
research Melatonin membrane receptors in peripheral tissues: Distribution and functions
Melatonin affects many body functions beyond sleep by interacting with specific receptors in various tissues.
research Biochemical Testing of the Thyroid: TSH is the Best and, Oftentimes, Only Test Needed – A Review for Primary Care
TSH is usually the only test needed to check thyroid function in primary care.
research Four days of simulated shift work reduces insulin sensitivity in humans
Working night shifts for four days can lower the body's ability to use insulin, which may increase the risk of type 2 diabetes.
research Measurement of hair growth
Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.
research The Rho GTPase exchange factor Vav2 promotes extensive age-dependent rewiring of the hair follicle stem cell transcriptome
Vav2 changes how hair follicle stem cells' genes work as they age, which might improve regeneration but also raise cancer risk.
research Effect of immunization against melatonin on seasonal fleece growth in feral goats
Immunizing goats against melatonin can temporarily change their cashmere growth cycles and increase fleece production.
